Abstract:The direct toxicity of insecticidal soap, horticultural oil, Azatin, an extract from the Neem tree containing azadiractin, and BotainiGard, a commercial formulation of the entomopathogenic fungus Beauveria bassiana, was assessed on adults of four species of coccinellids—Hippodamia convergens (Guérin-Ménéville), Coleomegilla maculata (DeGeer), Harmonia axyridis Pallas, and Cryptolaemus montrouzieri Mulsant. All biorationals caused less mortality than a conventional pesticide, carbaryl (Sevin). Horticultural oil (Sunspray ultrafine oil) consistently had no effect on beetle survivorship. Insecticidal soap (M-Pede) significantly reduced survival in all replicates for C. maculata and in at least one of the three replicates for the other three coccinellid species. Beauveria bassiana (BotaniGard) significantly reduced survival of C. montrouzieri at 72 h after spray in all three replicates. Azatin reduced survivorship in only one species, C. maculata, in only one of the three replicates.
